Feasibility Study Description
Final Report
Arnold Irrigation
The Arnold Irrigation District used this funding to evaluate the feasibility of piping 2 miles of an open channel canal that delivers irrigation water to 30 acres. Analyses included: conservation potential, seepage mitigation options, pipeline pressure and hydraulics, pipeline material recommendations (lining vs. piping), and a cost estimate. The estimated cost for implementing this project as recommended is ~$1.7 million dollars.
Benton County
Benton County worked with a number of partners to create a research facility for conducting field-scale experiments of green infrastructure (e.g., raingardens, bioswales, etc.) that can be used to slow down and treat stormwater. This project seeks to demonstrate the feasibility of alternate stormwater treatment and collection systems based on their performance and costs. Benton County, in collaboration with their partners, will test various methods for stormwater capture and treatment and share their findings through outreach materials.
City of Astoria
The City of Astoria used this funding to evaluate the stability of Bear Creek Dam for ground motions that would result from a Cascadia Subduction Zone earthquake using updated information on local geology as well as seismic hazards. Bear Creek Dam is a concrete gravity dam that impounds municipal water for the City of Astoria, Oregon. The overall objective of the study was to perform stability analyses that account for the stabilizing effects of basalt abutments. This study included a review of previous stability evaluations and as-built documents from City archives, development of a geologic model of the dam, laboratory testing on samples recovered during Phase 1 explorations (undertaken prior to this study), analysis of the stability of Bear Creek Dam under static and seismic loading, and an estimate of seismic displacement. The study revealed that there are still uncertainties about the right abutment due to limited subsurface data and unclear as-built sections and the report recommends additional explorations to refine the stability analysis.
City of Halfway
This study assisted the City of Halfway in identifying a viable effluent water reuse site to help the City attain compliance with their wastewater treatment permit. The study identified potential reuse sites by first identifying key design considerations, locating candidate parcels, and conducting a public information campaign to generate interest and to solicit landowners interested in water reuse. The Study then proceeded with investigating the sites owned by interested landowners and gaining an understanding of the owners' water reuse objectives. From this information, conceptual designs for water storage sites and irrigation facilities were prepared for comparison. This Study closes with an outline of the actions necessary to implement the proposed water reuse project.
City of Newport
The City of Newport used this funding to conduct a phase 3 assessment of the static and seismic stability of Big Creek Dam No. 1 and Big Creek Dam No. 2 (BC 2). Big Creek Dam No. 1 and No. 2 are earthen dams that provide municipal water to the City of Newport. This assessment included 1) an update for the seismic hazard characterization of the site and an update of the seismic time histories based on the most recent research; 2) additional site characterizations including borings and cone penetration testing, sampling and laboratory testing; 3) analysis and evaluation of the field and laboratory test results; 4) developing a more detailed and comprehensive geologic model of the two dam sites along with generalized profiles and cross-sections for engineering evaluations; 5) an update of the previously completed seepage, static and post-earthquake stability analysis; 6) evaluating the seismic response (deformations) of both existing dams in response to a range of potential earthquakes at the site;
7) developing and evaluating alternatives for corrective actions at both dams;
8) development of decision level cost estimates for the corrective action concepts; and
9) providing a preliminary environmental permitting overview for the corrective actions.
Central Oregon
Irrigation District
The Central Oregon Irrigation District used this funding to evaluate the feasibility of piping an open channel canal that delivers irrigation water. Analyses included: field seepage loss measurements (estimated at ~5cfs), detailed cross-sectional field survey, an updated cost analysis, development of 80% design drawings and an updated permitting assessment. The study found that this project continues to be feasible. The estimated cost for implementing this project as recommended (using labor provided by the COID) is ~$1 million dollars. Update: This project has been implemented.
East Valley
Water District
The East Valley Water District used this funding to collect updated hydrologic information on a proposed storage site. This technical report is an update of the October 2012 report on hydrologic data collected on Drift Creek and nearby streams as part of a feasibility study for a proposed reservoir that would store runoff from Drift Creek. The primary objective of the hydrologic analysis is to continue to evaluate the relationship between Drift Creek and other streams in terms of discharges, watershed characteristics, rainfall-runoff distribution, and to determine how best to use that information to develop the expected project inflow that considers as many run-off conditions as possible. The report also continues to evaluate the daily operation of the reservoir under several plausible scenarios controlled by reservoir inflow, mandatory release requirements, irrigation needs, etc. to help solidify an acceptable release strategy.
Watershed Council
The Fifteenmile Watershed Council used this funding to determine the feasibility of implementing an off-channel aboveground storage facility in the Fifteenmile Creek watershed to benefit fish and farms. The intent of this storage facility is to enhance stream flows and reduce stream water temperatures by allowing water to remain in the stream that is typically diverted for irrigation and replacing the irrigation water with water from the aboveground storage facility. The study included evaluations of: hydrologic characteristics of the source stream, physical feasibility of aboveground storage sites, temperature evaluation, regulatory feasibility, economic feasibility, efficiency gains and conservation potential, and environmental benefits and impacts.
Hood River SWCD &
East Fork Irrigation District
The East Fork Irrigation District used this funding to assess water conservation and system improvements. The system improvement plan includes a review of existing conditions, an evaluation of a proposed telemetry monitoring and control system including a list of basic monitoring sites, and development of a list of potential improvement projects including identification of water conservation and hydroelectric opportunities as well as cost estimates.

Irrigation Canal Co. &
Union SWCD
The Irrigation Canal Company used this funding to assess water conservation and system improvements. The water conservation assessment includes an evaluation of the existing system, evaluation of proposed improvements to this system, conceptual designs, and cost estimates. The design alternatives include methods for improving the water efficiency of the irrigation canal while also improving fish passage conditions along the Grande Ronde River.

Below Ground
The National Park Service (NPS) used this funding to evaluate the feasibility of developing a new groundwater supply for potable uses at Crater Lake National Park (CRLA). This study included design and construction of an exploratory well to test a potential groundwater source and also assessed the feasibility of using a well for aquifer storage and recovery or artificial recharge.
Walla Walla Watershed

Storage -
Below Ground
The Walla Walla Watershed Council used this funding to he purpose of this assess the feasibility of aquifer storage and recovery as a means to supplement irrigation and augment stream flows. The study included drilling five exploratory wells to better understand subsurface hydraulic properties and groundwater flow conditions, including groundwater levels and temperature.
Walla Walla
Watershed Council
The Walla Walla Watershed Council used this funding to evaluate the cost and feasibility of extending the Walla Walla River Water Exchange project to irrigators on the Oregon side of the Walla Walla basin.  The purpose of the Walla Walla River Water Exchange is to reduce irrigation surface water withdrawals from the Walla Walla River. This would be accomplished by supplying water from the Columbia River  directly to irrigation distribution systems located in the upper Walla Walla River Basin, thus leaving more of the natural flows in the river. Two initial studies were undertaken by the Army Corps of Engineers, but the project proponents were interested in seeing the proposals and associated costs proposed by non-federal/private entities. In addition, this study provides an initial evaluation of placing a storage dam in the Pine Creek Drainage, including an analysis of how that would interact with the existing system.
